Sermorelin
One of the most prescribed GH peptides. Copies the first 29 amino acids of natural GHRH, triggering physiological GH pulses from the pituitary.

Top benefits
Week 1–2
Improved sleep quality, particularly deep sleep phases. Mild increase in morning energy. GH pulses beginning to normalize.
Week 3–6
Better recovery from exercise. Subtle fat loss and improved muscle tone. Improved skin hydration and elasticity. Enhanced sense of well-being.
Week 8+
Significant body composition improvements. Joint and connective tissue health enhanced. Normalized GH/IGF-1 axis. Sustained sleep and recovery benefits.
Common Side Effects
Scientific Overview
Sermorelin is a synthetic 29-amino acid GHRH analog. FDA-approved for pediatric GH deficiency. Maintains normal GH pulsatility without suppressing endogenous GHRH. Clinical studies show improvements in body composition, slow-wave sleep, and IGF-1 normalization.
Dosing
200-300 mcg subq before bed, daily. Give it 3-6 months for best results.

Stacks Well With
Ipamorelin
One of the cleanest GH boosters. Stimulates growth hormone release without affecting cortisol or prolactin, meaning fewer side effects than other GH peptides.
GHRP-6
GH booster that significantly increases appetite by mimicking ghrelin. Good for bulking or anyone who struggles to eat enough.
GHRP-2
Stronger GH release than GHRP-6, with more moderate appetite increase. Raises both GH and IGF-1, though it can slightly bump cortisol and prolactin.
MK-677 (Ibutamoren)
Orally active ghrelin receptor agonist (not a peptide). Boosts growth hormone and IGF-1. Known for improving deep sleep, increasing appetite, and gradually improving body composition.
CJC-1295 with DAC
Long-lasting growth hormone booster. The DAC modification keeps it active for days, producing steady GH elevation for muscle growth, fat loss, and recovery.
Compare
CJC-1295 and Sermorelin are both GHRH analogs that stimulate growth hormone release through the same receptor pathway. The key difference is that Sermorelin was the first GHRH analog with decades of clinical use, while CJC-1295 is a newer modified version designed for a much longer half-life.
Sermorelin vs Tesamorelin: GH Peptide ComparisonSermorelin and Tesamorelin are both GHRH (growth hormone-releasing hormone) analogs that stimulate the pituitary gland to produce growth hormone. Despite sharing the same fundamental mechanism, they differ significantly in regulatory status, clinical evidence, half-life, and cost. Sermorelin is a well-known compounded peptide with decades of use, while Tesamorelin is the only GHRH analog currently holding active FDA approval -- specifically for HIV-associated lipodystrophy.
